Anticipated Impact


ACCESS -The entire project area will be closed, starting October 3, 2016.

  • The main trail from the tennis courts to Wakefield Drive will be closed.
  • There will be no public access across the park between the tennis courts and Wakefield Drive.
  • Each of the four playgrounds in the parkland will remain open throughout the construction
  • Access to the parkland from Aunt Lilly La and Ossian Hall La will remain open.
  • There will be three points for construction access to the project area from public streets. These will be:
    • From the south TCC parking lot near the tennis court gazebo
    • Along Elizabeth Lane below Mary Lee Lane – (This entrance to the parkland will be completely blocked.)
    • Wakefield Drive near the stream crossing
  • The lower portion of the south TCC parking lot will be blocked but pedestrian access to the gazebo and tennis courts will be maintained.


  • There will be noise from the construction equipment operating in the parkland.
  • Most work will be done during weekdays, although the contractor can work on weekends or Federal holidays.
  • The contractor will be on site at 6:30 am but will not operate equipment before  7 am (9 am on weekends and Federal holidays).
  • The work day will generally end in the late afternoon, but the contractor can work until 9 pm if needed.


  • There will be loss of existing trees but the design has been tailored to save as many healthy, mature trees as possible.
  • Equipment access paths have been designed to minimize damage to trees.
  • The chance of damage to root structures of healthy trees near construction access paths will be minimuzed by using protective matting


  • Paths within the construction area will be replaced with new 6-foot wide asphalt paths.
  • (Separately, THA intends to refurbish the remaining parkland paths immediately following the stream restoration project.)
  • All bridges, except Golden Gate bridge, in the project area will be replaced with a different design bridge.
  • Golden Gate bridge will be eliminated.
  • The asphalt paths will be sloped as necessary for the approaches to the bridges,with handrails where the slope is steeper than 10% grade.
  • All bridge approaches will be sloped less than many of the current wooden approach ramps.


  • Streambanks will be planted with native vegetation through biodegradable matting that protects the banks from erosion until the vegetation can be established.


  • Native trees and shrubs will be planted. The seedlings will initially be only a few feet high. Some may be protected by screens from deer grazing.
